Hello Emma and thank you for bringing such a festive question to the Disney Parks Moms Panel.
Oh my goodness what a magical Christmas and milestone birthday surprise holiday you're planning for your lucky family, you must be just about bursting with excitement!
A memorable trip on Christmas Eve in 'a one horse opened sleigh' with a
Holiday Sleigh Ride at Disney's Fort Wilderness Resort and Campground might be a fun idea. Reservations are highly recommended for this popular seasonal treat and can be made 180 days in advance by speaking with a Cast Member on 0800 16 90 730; although it's worth pointing out that a family of 6 will require 2 x sleighs.
Perhaps you could allow the lovely folks at
Disney Floral and Gifts to help arrange an extra special surprise on Christmas Day; there are plenty of delightful gifts or in-room celebrations to choose from and something to suit most budgets.

I'm sure whatever is finally decided upon you'll enjoy a magical holiday making memories with your dear family which will last an entire lifetime.
If I can help sprinkle any extra pixie dust onto your 2015 Christmas holiday to Walt Disney World Resort please pop back to ask me another question.
Have a great Disney day.
